Description
- This is a Continuation-In-Part of PCT/EP2005/051407 filed 29 Mar. 2005, which designated the US, and which claimed priority from French patent application No. 04/03780 filed 9 Apr. 2004.
- The present invention relates to an electrical switch.
- The invention relates more particularly to an electrical switch of the normally closed type comprising:
-
- a casing which carries a pair of fixed contact elements each of which comprises a contact head which delimits a front transverse fixed contact surface and which is arranged inside the casing in such a way that the two fixed contact surfaces are longitudinally aligned:
- a contact bar, forming a movable contact, which runs transversely opposite the two fixed contact surfaces and which is mounted movably, according to a horizontal longitudinal direction, between:
- at least one rear closure position in which a rear contact surface of the contact bar is in contact bearing on the said fixed contact surfaces so as to establish an electrical link between the two fixed contact elements of the switch;
- and a front opening position in which the said rear contact surface is offset longitudinally towards the front in such a way as to interrupt the said electrical link;
-
- and a member for actuation of the movable contact bar which is mounted so as to slide longitudinally in the casing between:
- at least one rear rest position in which it is in abutment against a portion of the casing and in which the movable contact bar is in its rear closure position;
- and a front triggering position in which the movable contact bar is in its front opening position;
- the moveable contact bar and the actuation member constituting a movable assembly, and the switch comprising a return spring which co-operates with the movable contact bar so as to urge it towards its rear closure position.
- A switch of this type is known from document DE-A-3,138,379.
- In addition, it allows no modularity in the switch design, especially as regards the use of various light sources and/or the electrical connection and supply circuits for the light sources.
- In order to afford it great stability of contact in the normally closed position, the switch according to the present invention is characterized in that the movable contact bar is mounted rocking on the actuation member about an upper transverse axis, the actuation member comprises a front face for driving the movable contact bar towards which the bar is returned by the spring, and the said front drive face is offset longitudinally towards the rear with respect to the contact bar when the bar is in its rear closure position and when the actuation member is in its rear rest position.
- According to other characteristics of the invention:
-
- the said front drive face is able to co-operate with a portion of the rear contact surface of the movable contact bar;
- the said portion of the rear contact surface of the movable contact bar is situated between two transverse end portions each of which bears on an associated fixed contact surface when the bar is in its rear closure position;
- the said rear contact surface is a surface in the form of an arc of a convex cylinder of transverse axis, and the said front fixed contact surfaces are vertical plane surfaces;
- the actuation member comprises a horizontal central finger for guiding the return spring which runs towards the front through a corresponding notch of the movable contact bar, and the return spring is a spiral compression spring through which the guiding finger passes, the front longitudinal end of which bears on a wall of the casing, and the rear longitudinal end of which bears on a front face portion of the movable bar;
- the actuation member is able to occupy a so-called overtravel position which is offset longitudinally towards the front with respect to its front triggering position;
- the switch exhibits a general symmetry of design with respect to a vertical and longitudinal mid plane.
- Other characteristics and advantages of the invention will become apparent on reading the detailed description of a preferred embodiment of the invention for the understanding of which reference may be made to the appended drawings.

- The front, rear orientation would also be used according to the left, right orientation of FIGS. 5 to 9.
- The
switch 10 illustrated in the figures is an electric switch of the normally closed type which exhibits a symmetry of design and embodiment with respect to a vertical mid plane of longitudinal orientation PVM. - It comprises a main body or
casing 12 of right-angled parallelepipedal general shape delimited by two opposite verticallateral walls 14, a front transversevertical wall 16, a rear transversevertical wall 18 which comprises a centred rectangularvertical window 20 which emerges into its freeupper edge 22, and by ahorizontal bottom wall 24. - The open
upper face 26 of thecasing 12 is closed by complementaryupper lid 28 in the form of a horizontal plate whose rear transverse edge 30 comprises apolarization lug 32 which, in the lid mounted position and as may be seen for example inFIG. 1 , is received in the upper part of thewindow 20. - The
walls bottom 24 and theupper lid 28 delimit aninternal cavity 34 in which various components of theswitch 10 are arranged. - The casing is embodied by moulding from insulating plastic and it extends, vertically to the rear, beyond the
lower face 36 of thebottom 24, via ablock 38 narrower in the longitudinal direction, and which comprises two emergentvertical slots 40. - The
switch 10 comprises two fixedcontact elements 42 made of an electrically conducting material each of which is embodied by blanking from a vertical plate of transverse orientation. - Each
fixed contact element 42 comprises alower rod 44 which is received through an associatedslot 40 and which projects vertically downwards beyond thelower face 39 of thelower block 38 so as to constitute an electrical connection terminal of the switch, for example for connection with a printed circuit board, not represented. - Each
fixed contact element 42 comprises anupper contact head 48 which is arranged inside theinternal cavity 34 of thecasing 12 and in which it is positioned with accuracy and immobilized in position. - Each
contact head 48 comprises, in its transversely interiorvertical edge 50, anaperture 52 corresponding to thewindow 20, while its transversely exteriorvertical edge 54 is received in agroove 56 of theinterior face 15 of the associatedlateral wall 14. - The
front face 58 of eachcontact head 48 constitutes a fixed contact surface and the twosurfaces 58 are substantially co-planar and of transverse vertical orientation. - The
switch 10 comprises an actuation member oractuator 60 which comprises afront body 66 arranged inside theinternal cavity 34 and a rear operating pusher orbutton 62. - The
pusher 62 is of rectangular cross section complementary to thewindow 20 through which it projects longitudinally towards the rear in such a way that at least its reartransverse face 64 is permanently situated outside thecasing 12 so as to allow actuation by acting on said face, from the rear to the front in the direction indicated by the arrow F3. - The
pusher 62 is embodied in one piece by moulding from an insulating plastic together with thefront body 66. - The
front body 66 comprises a sturdy rearcentral part 68 whoserear face 70 bears against opposite portions of the interior face of therear wall 18 when theactuation member 60 is in its rear rest position illustrated in FIGS. 3 to 7. - This
central part 68 comprises two opposite vertical andtransverse wings 72 of smaller longitudinal thickness than thecentral part 68 and each of which comprises a fronttransverse face 74 of vertical orientation which constitutes a part of the front face of the actuator for driving the movable contact element of the switch which will be described hereinbelow. - Between the two
wings 72, the central part comprises a centralhorizontal finger 76 which runs longitudinally towards the front and, underneath thefinger 76, a longitudinal centrallower branch 78 for guiding and positioning thefront body 66 which slides on theupper face 25 of thebottom wall 24. - To supplement the guiding by longitudinal sliding of the
body 66 in thecavity 34, the former comprises on the one hand an upper horizontal partition orroof 82 whose horizontalupper face 84 slides along thelower face 29 of thelid 28 and, on the other hand, two opposite upperlateral branches 86 which run horizontally towards the front and each of which comprises an exterior verticallateral face 88 which slides along theinternal face 15 of the correspondinglateral wall 14 of thecasing 12. - Thus, the
front body 66 is perfectly guided by longitudinal sliding in theinternal cavity 34. - Finally, the front body comprises two
housings 92 forming bearings of common horizontal and transverse axis A. - Each bearing 92 is arranged projecting along the internal vertical
lateral face 90 of alateral branch 86 and under theroof 82. - Each bearing 92 is semi-cylindrical and it is open longitudinally towards the front.
- The
movable contact element 94 of theswitch 10 is embodied in the form of a rocker made of a conducting material which is embodied by blanking, forming and blowing from a thick plate. - The
rocker 94 comprises a lowermovable contact bar 96 and anupper articulation part 98 for its rockable mounting on thefront body 66 of theactuator 60, about the axis A. - The lower
movable contact bar 96 runs horizontally and transversely inside thecavity 34. - In cross section through a longitudinal vertical plane, it exhibits a globally bowed profile in the form of a cylindrical arc and it is thus delimited by a convex inwardly curved rear face which constitutes the
rear contact surface 100 of themovable bar 96 which is able to co-operate with thefixed contact surfaces 58. The central part of thecontact bar 96 comprises anotch 102 which is open towards the bottom for the passage of the horizontalcentral finger 76. Theupper articulation part 98 of therocker 94 comprises two opposite co-axiallateral journals 104 each of which is received rotatably in asemi-cylindrical bearing 92. - The
switch 10 finally comprises aspiral compression spring 108 through the rear part of which thefinger 76 for guiding the spring passes longitudinally. The spring is mounted compressed longitudinally between the frontconcave bent face 97 of thecontact bar 96 against which it bears via itsrear end turn 114 and an opposing portion of theinternal face 17 of the fronttransverse wall 16 against which it bears via itsfront end turn 112. - The guidance of the
return spring 108 is moreover ensured by alower stud 116 of thecover 28 and by two internallateral studs 118 of thecasing 12. - When the
rocker 94 is mounted on thefront body 66, it constitutes together with the latter an assembly that is longitudinally movable in theinternal cavity 34. - For this purpose, the
return spring 108 forces thejournals 104 into the depths of thebearings 92 permanently. - In the rear rest position, and as may be seen in FIGS. 5 to 7, the dimensions and the arrangement of the various components are such that the front faces 74 for driving the
actuation member - Consequently, the
rear face 100 bears longitudinally, via its opposite transverse end spans or portions, on the fixed contact faces 58 with a high contact pressure due to the action of thereturn spring 108. - In this position, the electrical link between the two fixed
contact elements 42 is closed by thecontact bar 96 and theswitch 10 is thus of the so-called normally closed type NF at rest, that is to say when no action is exerted on thepush button 62. - In this rest position of the
actuator 60 and closure position (of the link) of themovable contact bar 96, therocker 94 is in an angular position, about its axis A, in which the rear face 99 of itsupper articulation part 98 forms an acute angle alpha with respect to the vertical which, in the example illustrated inFIG. 7 , is around 16°30′. - From this position, by exerting an actuation force along the arrow F3 on the
rear face 64 of thepush button 62, thefront body 66 moves longitudinally towards the front against the force exerted by thereturn spring 108. - During this actuation travel, the journals remain supported in the bearings and the
upper part 98 moves with thefront body 66, while therocker 94 rocks progressively in the anti-clockwise direction so as to reach the position illustrated inFIG. 8 . - In this so-called triggering position of the
switch 10, the front actuation faces 74 have reached the opposing portions of the convexrear face 100 of themovable contact bar 96 so that they are henceforth mutually supported. - On completion of this actuation travel, or triggering travel (very short of the order of 0.4 mm) the angle alpha is of the order of 26°. This angle is henceforth a maximum since the
rocker 94 can no longer pivot further with respect to thefront body 66. - Between the rear rest position and the position of triggering of the switch, the
movable contact 94 rubs on the two contact heads 48 during the rocking thereof. This rubbing of themoveable contact 94 ensures self-cleaning of the contact surfaces. - Once the forward travel continues, the rear
transverse contact face 100 of themovable contact bar 96 leaves the front fixed contact surfaces 58 of theheads 48, interrupting the electrical link between thecontact elements 42. The bar thus occupies its front position, so-called opening position (of the electrical link). - As may be seen by comparing
FIGS. 8 and 9 , it is possible to apply to thepush button 62, and hence to theactuation member 60, an overtravel of actuation according to the arrow F3 which here is a maximum of 1.6 mm, i.e. a maximum total travel of the button of the order of 2 mm. This position is determined in particular by the coming into abutment of the front free ends 87 of the upperlateral branches 86 against the opposing portions of theinternal face 17 of the fronttransverse wall 16. - When the user relaxes his action on the
push button 62, and under the action of thereturn spring 108 which acts permanently on thecontact bar 96 and hence on thefront body 66 of theactuator 60, the movable assembly 60-94 recoils rearwards, passing again through the position illustrated inFIG. 8 in which the electrical link is again established by the coming into contact of the movable contact bar 96-100 with the front fixed contact surfaces 58. - Thereafter, the
bar 96 no longer moves longitudinally towards the rear and it is therocker 94 which rocks in the clockwise direction to compensate for the end of travel of the actuator 60-66 until its rear rest position illustrated inFIG. 7 . - By virtue of the design according to the invention, one ensures very good contact pressure of the
movable contact bar 96 on the fixed contacts 48-58 and very good stability of the contact until the opening of the electrical link.
